You folks are smart, you certainly know your flies.
Ran the specimen through Whitworth's key, definitely Calliphora. Got to couplet 5 in species key, critical character is number of postsutural intra-alar setae. 2 in vicina and vomitoria and some other species. My specimen has 3 = livida or coloradensis, the black genal dilation keys to livida vs. reddish dilation in coloradensis.
Thanks to you all for comments.
